Method of roof covering with roof covering elements (tile-like sheets)

ABSTRACT

Method of a roof covering with roof covering elements (tile-like sheets), in which the lower transversal step has got fixing sunken embossing well-fitting to the bend of the upper transversal step of an adjacent roof covering element placed over the former one, performed according to fixed procedure, preferably with use of prefabricated assembling embossments and holes, exploiting embossments at a corner of the roof covering element and an element fixed to a roof with mounting device at one end and its the other end clamps an edge of the roof covering element to the roofing characterised in that the left edge ( 1.1 ) of an initial sheet ( 1 ) stabilized by fastening with at least one screw to a roof batten ( 3 ) is covered by the right edge ( 4.1 ) of the second sheet ( 4 ). The sheets are mounted by a screw placed through the right lower assembling hole ( 4.2 ) of the second sheet ( 4 ) and the left lower assembling hole ( 1.2 ) of the initial sheet ( 1 ). Then the second sheet ( 4 ) is stabilized by mounting at least of one screw to a roof batten ( 3 ). The lower edge ( 5.1 ) of the third sheet ( 5 ) is put onto the upper edge ( 1.3 ) the initial sheet ( 1 ). These sheets are mounted by a screw placed through the right lower assembling hole ( 5.2 ) of the third sheet ( 5 ) and the right upper assembling hole ( 1.4 ) of the initial sheet ( 1 ). and at the same time, the left lower assembling hole ( 5.3 ) of the third sheet ( 5 ) appears over the right upper assembling hole ( 4.3 ) of the second sheet ( 4 ). Then the right edge ( 6.1 ) of the fourth sheet ( 6 ) is put onto the left edge ( 5.4 ) of the third sheet ( 5 ), whilst the lower edge ( 6.2 ) of the fourth sheet ( 6 ) is placed onto the upper edge ( 4.4 ) of the second sheet ( 4 ). The fourth ( 6 ) and the second ( 4 ) sheets are mounted by a screw applied through, preferably, the middle lower assembling hole ( 6.6 ) of the fourth sheet ( 6 ) and through the middle upper assembling hole ( 4.8 ) of the second sheet ( 4 ). The junction comprised of corners of four sheets is mounted with a screw applied through the right lower assembling hole ( 6.4 ) of the fourth sheet ( 6 ), the left lower assembling hole ( 5.3 ). of the third sheet ( 5 ), the right upper assembling hole ( 4.3 ) of the second sheet ( 4 ) and through the left upper assembling hole ( 1.5 ) of the initial sheet ( 1 ). Every time, the bend ( 5.7 ) or ( 6.7 ) preferably straight—of the lower edge end ( 5.1 ) or ( 6.2 ) of a sheet put onto a covered one, is placed in a semicircular deflection ( 1.6 ) or ( 4.9 ) of the sheet to be covered.

The present invention relates to a method of a roof covering with roofcovering elements (tile-like sheets).

A roof cladding element and method for manufacturing roof claddingelements is known from the US patent description no. U.S. Pat. No.7,690,169B2. The roof cladding element has been manufactured of profiledplate material. Such manufactured elements are adjacently and insuccession mountable such that the edges of a roof cladding element willbe placed a distance overlapping with the edges of adjacent roofcladding elements. At least one corner of a roof cladding material hasgot recess reaching partly lower than the lower surface of the element.

A roof cladding element with a hidden fastening, in which a lowertransversal step has got a fastening nest adjusted to Z-shaped recess ofthe upper transversal step of an adjacent roof cladding element placedover the previous one, is known from the international patentapplication no. WO2006018472A1.

From Polish patent description no. PL206210 there is also known afastening device comprising a strip member of comparatively short lengthand a securing means for securing to the roof covering free edge of amanually deformable flashing skirt characterized by the strip member atone end is secured to the roof covering with the securing means, whilethe other end is pressed down the free edge of the flashing skirtagainst the roof covering.

There is known from the Polish patent application no. P403087 a roofcovering element (tile-like sheet) equipped with a cramp, characterizedby that a plane of the roof covering element endings at wave-likeembossing of the surface of the upper edge has got at least oneincision, preferably done in a part without assembling hole andpreferably of rectangle shape, in which there is applied the cramp.Incision width is bigger than cramp width.

Method of a roof covering with roof covering elements (tile-like sheets)according to this invention characterises in that the left edge of aninitial sheet stabilized by fastening with at least one screw to a roofbatten is covered by the right edge of the second sheet and the sheetsare mounted by a screw placed through the right lower assembling hole ofthe second sheet and the left lower assembling hole of the initialsheet. Now, the second sheet is stabilized by mounting at least of onescrew to a roof batten. Thereafter, the lower edge of the third sheet isput on the upper edge the initial sheet, and these sheets are mounted bya screw placed through the right lower assembling hole of the thirdsheet and the right upper assembling hole of the initial sheet. At thesame time, the left lower assembling hole of the third sheet appearsover the right upper assembling hole of the second sheet. Now, the rightedge of the fourth sheet is put onto the left edge of the third sheet,whilst the lower edge of the fourth sheet is placed onto the upper edgeof the second sheet. The fourth and the second sheets are mounted by ascrew applied through middle lower assembling hole of the fourth sheetand through, preferably, the middle upper assembling hole of the secondsheet. Next, a junction comprised of corners of four sheets is mountedwith a screw applied through the right lower assembling hole of thefourth sheet, the left lower assembling hole of the third sheet, theright upper assembling hole of the second sheet and through the leftupper assembling hole of the initial sheet. Every time, abend—preferably straight—of the lower edge end of a sheet put onto acovered one, is placed in a semicircular deflection of the sheet to becovered.

The lower edge of a following sheet is placed onto the upper edge of thethird sheet, and these sheets are mounted with a screw applied throughthe right lower assembling hole of the following sheet and through theright upper assembling hole of the third sheet.

Simultaneously, the left lower assembling hole of the following sheetappears over the right upper assembling hole of the fourth sheet. Everytime, a bend—preferably straight—of the lower edge end of the followingsheet is placed in a semicircular deflection of the third sheet to becovered. Further mounting of sheets is according to the aforementionedassembling procedure, in which the following sheet is to be consideredas the third one.

The right edge of a next sheet is placed onto the left edge of thesecond sheet and these sheets are mounted with a screw applied throughthe right lower assembling hole of the next sheet and through the leftlower assembling hole of the second sheet. Simultaneously, the rightupper assembling hole of the next sheet appears over the left upperassembling hole of the second sheet and under the left lower assemblinghole of the fourth sheet. Further mounting of sheets is according to theaforementioned assembling procedure, in which the next sheet is to beconsidered as the second one.

In other version of the invention, an initial sheet or the second sheetor the third sheet or the fourth sheet or the following sheet or thenext sheet is fixed with at least one cramp to a roof batten.

Every time the bend edge of a cramp is placed in a semicirculardeflection of the initial sheet or in a semicircular deflection of thesecond sheet or in a semicircular deflection of the third sheet or in asemicircular deflection of the fourth sheet or in a semicirculardeflection of the following sheet or in a semicircular deflection of thenext sheet.

Method of a roof covering with roof covering elements (tile-like sheets)according to this invention provides ideal mounting of all sheets duringeasy and quick assembly. There is no need for extra fitting of sheets,as every sheet can be applied in any place. The roof covering can beperformed in any direction: upwards and to left or right from thebottom, or downwards and to left or right from the top. If needed, themethod of a roof covering according to this invention enables easyreplacement of damaged part of a roof by dismantling only the sheetsnearest to the damaged piece.

The roof done according to this invention enables free dropping down ofcondensed water and free air circulation, what results in lower risk ofcorrosion.
